GUCY2D (Retinal guanylyl cyclase 1) variants and mutations

GUCY2D (also known as Retinal guanylyl cyclase 1) is a human protein-coding gene encoding a retinal guanylyl cyclase 1 protein. A retinal guanylate cyclase that restores cGMP levels in rod and cone photoreceptors during visual signaling. Biallelic pathogenic variants commonly cause Leber congenital amaurosis, while certain dominant variants cause cone-rod dystrophy. This analysis covers 2,034 GUCY2D variants and mutations. Of these, 98% have computational variant effect predictions. Disease context includes Leber congenital amaurosis 1, cone-rod dystrophy 6, and Leber congenital amaurosis. Example GUCY2D variants include M1I, M1K, and M1V.
